Runtime (operating hours counter)
Total system runtime
The total system runtime is indicated in r2114 (Control Unit), and comprises data from
r2114[0] (milliseconds) and from r2114[1] (days).
Index 0 indicates the system runtime in milliseconds; after reaching 86,400,000 ms
(24 hours) the value is reset. Index 1 indicates the system runtime in days.
The value is saved when the system is switched off.
Once the drive unit has been switched on, the counter continues to run with the value that
was saved the last time the drive was switched off.
Relative system runtime
The relative system runtime since the last POWER ON is displayed in p0969 (Control Unit).
The value is indicated in milliseconds and the counter overflows after 49 days.
Actual motor operating hours
The motor operating hours counter p0650 (drive) is started when the pulses are enabled.
When the pulse enable is withdrawn, the counter is stopped and the value saved.
The counter is deactivated with p0651 = 0.
If the maintenance interval set in p0651 is reached, alarm A01590 is triggered. Once the
motor has been maintained, the maintenance interval must be reset.
Note
If the motor data set is switched during the star/delta changeover without the motor being
replaced, the two values in p0650 must be added to determine the correct number of motor
operating hours.
Operating hours counter for the fan
The operating hours of the fan in the power unit are displayed in p0251 (drive).
In this parameter, the number of elapsed hours can only be reset to 0 (e.g. after a fan has
been replaced).
The service life of the fan is entered in p0252 (drive).
Alarm A30042 (service life of the fan reached or exceeded) is output when this figure is
reached, and also 500 hours beforehand. Evaluation of the fault value in the alarm provides
details of the cause of the alarm.
Monitoring is deactivated with p0252 = 0.
